Abstract

The T-handle hexagonal key wrench set and base can be disassembled and piled up before use, thus decreasing the volume thereof. This feature is especially suited for mass transportation and saves transportation costs. Also, each bearing plate is securely interlockable by use of interconnecting insertion plates. These interlocking insertion plates allow quick, secure assembly into a functional " " shape.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. A composite base for a hexagonal key wrench set, said base comprising: a substantially L-shaped lower bearing plate having vertical and horizontal legs;   first connecting means at the free end of said vertical leg of said lower bearing plate;   a substantially flat middle bearing plate having a pair of spaced opposed edges;   a pair of second connecting means, one each of said pair of second connecting means at each one of said pair of spaced opposed edges of said middle bearing plate;   a first plurality of through holes in said middle bearing plate for receiving a hexagonal key wrench therethrough;   a substantially L-shaped upper bearing plate having vertical and horizontal legs;   third connecting means at the free end of said vertical leg of said upper bearing plate;   a second plurality of through holes in said horizontal leg of said upper bearing plate; and   said first connecting means being connectable with one of said pair of second connecting means, said third connecting means being connectable with the other one of said pair of second connecting means, said first plurality of through holes in said middle bearing plate being aligned with said second plurality of through holes in said upper bearing plate when said third connecting means is connected to said other one of said second connecting means for receiving a plurality of hexagonal key wrenches therethrough.   
     
     
       2. A device as in claim 1, wherein each said first and third connecting means includes a first plurality of interlockable insertion plates, and said second connecting means includes a second plurality of interlockable insertion plates. 
     
     
       3. A device as in claim 2, wherein each of said first and second plurality of interlockable insertion plates includes a plurality of interlockable projections. 
     
     
       4. In combination, a plurality of hexagonal key wrenches and a base for receiving said plurality of hexagonal key wrenches, said base comprising: a substantially L-shaped lower bearing plate having vertical and horizontal legs;   first connecting means at the free end of said vertical leg of said lower bearing plate;   a substantially flat middle bearing plate having a pair of spaced opposed edges;   a pair of second connecting means, one each of said pair of second connecting means at each one of said pair of spaced opposed edges of said middle bearing plate;   a first plurality of through holes in said middle bearing plate for receiving a hexagonal key wrench therethrough;   a substantially L-shaped upper bearing plate having vertical and horizontal legs;   third connecting means at the free end of said vertical leg of said upper bearing plate;   a second plurality of through holes in said horizontal leg of said upper bearing plate; and   said first connecting means being connectable with one of said pair of second connecting means, said third connecting means being connectable with the other one of said pair of second connecting means, said first plurality of through holes in said middle bearing plate being aligned with said second plurality of through holes in said upper bearing plate when said third connecting means is connected to said other one of said second connecting means for receiving said plurality of hexagonal key wrenches therethrough.   
     
     
       5. A device as in claim 4, wherein each said first and third connecting means includes a first plurality of interlockable insertion plates, and said second connecting means includes a second plurality of interlockable insertion plates. 
     
     
       6. A device as in claim 5, wherein each of said first and second plurality of interlockable insertion plates includes a plurality of interlockable projections.
